vice) and are mounted on a carrier frame as a unit, and the object of the present invention is achieved by this characteristic. According to the present invention, a single device can be constructed with low spatial requirements, and at the same time enables binding or blocking using static electricity. This allows the machine required for handling the stacked prints to be made substantially smaller, while at the same time enabling binding and / or blocking depending on the current burden.

In addition, since the blocking device and the restraint device are identical as important components and the device according to the invention is economically manufactured, these components, such as transport bands, guide bands, abutments, etc. And pressing device (pre
ss-down-device) is used for both blocking and binding functions.

BRIEF DESCRIPTION OF THE DRAWINGS Advantageous embodiments of the invention are described and described in the drawings and the subclaims. According to a first advantageous embodiment of the invention, the conveyor device has a pair of guide bands, each transport band being guided around a roller having a vertical axis of rotation. These transport bands are arranged on both sides of the stack of prints, so that the stacking on the one hand and the transport on the other hand are achieved.

[0007] According to a further advantageous embodiment of the invention, the guide is designed to be essentially in a fixed position with respect to the stack. Except for the required alignment of these guides, the guides do not need to be moved for binding or blocking respectively. The blocking device has at least one electrode which is preferably integrated into the conveyor device. For example, electrodes are incorporated into the conveyor path of the lateral guide band. Similarly, it is possible to integrate the electrodes of the blocking device at the base of the conveyor path.

According to a further advantageous embodiment, a pressing device is provided, which cooperates with the blocking device and the binding device. In this case, a pressing device can be used for both the binding and blocking operations, the pressing device serving to compress the stack. The pressing device is preferably provided adjacent to the binding path of the binding device so that it does not interfere with the winding of the binding band.

In order to achieve alignment of the stack on its front side, it is preferred that a pivoting abutment for the stack is provided, spaced apart from the restraining path. As the abutment for the stack is designed to pivot, the abutment is particularly fast and structurally simple, guided in the conveyor path and the stack is stopped centrally at the abutment Align.

The guide band pairs extend to the binding path of the binding device so as to ensure that the stack is guided to the maximum possible extent. In addition, the conveyor device has a conveyor band on which the stack is placed and transported. The conveyor band is designed to be split into two or have openings so that the underlying electrode can be effective.

[0011] Furthermore, it is advantageous that an electrode pair is provided after the constraining path in order to achieve sufficient blocking. With the exception of the required alignment, this electrode pair is designed to be in a fixed position and at the same time acts as a mechanical guide for the stack. In the following, an exemplary method of an advantageous embodiment according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a perspective view of the device of the present invention. The illustrated device for handling stacked prints has a carrier frame 10 on which a conveyor device, a binding device and an electrostatic blocking device are mounted as a unit. For this purpose, the carrier plate 12 is mounted on a base frame 10, on which binding paths 14 of a binding device are arranged in sequence.

[0013] The conveyor device has conveyor bands 14 and 16, which are not illustrated in detail, by which the supplied stack is conveyed horizontally through the device.
On both sides of the conveyor bands 14 and 16 there are provided lateral guides 18 and 20, which are designed in a racecourse shape when viewed in cross section, and which integrate the integral guide bands 22 and 24. Have. Each guide band 22 and 24 is deflected around a roller (not shown) having a vertical axis of rotation, so that the guide bands 22 and 24 can grip the stack on its side, while the stack is It is conveyed and, on the other hand, it is arranged and guided.

In each case, each guide 18 and 20
And in the region of the guide bands 22 and 24, an elongated electrode 26 is provided. To this end, each guide band is led through a roller to the opposite side of the elongated electrode. The guides 18 and 20 are basically adjustable at the right angle to the conveyor path for alignment, but are not moved during transport of the stack or during blocking or binding, as it is in a fixed position. It means that it is designed.

A further electrode 28 cooperating with the electrode 26 is integrated into the carrier plate 12 between the conveyor bands 14 and 16. When viewed in the direction of the conveyor, the pressing device 30 that is lowered vertically from the position shown
, Which are for descending together and pushing the advanced stack.

When viewed in the direction of the conveyor after the constraining path 14, two more electrodes 32 and 34 are located on the carrier plate 12 and are moved perpendicular to the conveyor path for alignment only. These two electrodes are
Cooperates with further electrodes (not shown). Looking at the subsequent electrodes 32 and 34 in the conveyor direction, there is provided an abutment for the stack, which consists of two pivoting abutments 36 and 38. These abutments are pivotally disposed on the conveyor path of the stack and are positioned such that the stack is stopped centrally below the constrained path.

Reference numeral 40 indicates a receiving drum for binding band supply. Handling of stacked prints by the apparatus of the present invention begins, for example, with transport from a cross stacker to conveyor bands 14,16. Before processing the stack, guides 18 and 20, electrodes 32 and 3
4 and abutment pieces 36 and 38 are subjected to essential position adjustment. As the stack passes through the apparatus, the stack is guided laterally by guide bands 22 and 24 and simultaneously advanced in the conveyor direction. The stack is then slowed down and transported to abutments 36 and 38 to align the stack. Here, the stack is located centrally below the pressing device. The pressing device 30 then pushes the stack and squeezes air out of the stack. Simultaneously or with a slight time delay, an electrostatic blocking or binding process is performed. After the blocking or restraint is completed, the abutment pieces 36 and 38 are pivoted aside, respectively, and the conveyor bands 14, 16
Accelerates again, and the compressed and constrained stack is transferred to the next step.

It should be pointed out that the pressing device 30 is further provided with electrodes. Further, the contact portion formed by the contact pieces 36 and 38 also
It can be made in a structurally different way.
